分子式:
CAS号:

性质:由美国凯洛格公司开发的一种超短停留时间烃类热裂解制乙烯的管式裂解炉。物料在反应管内停留时间<0.1s。每台裂解炉中设有多组炉管,每组炉管由并联的多根(约12根)小直径(内径25~35mm)单程辐射管组成,垂直悬挂于辐射段中间。采用底部烧嘴双面辐射传热,燃料可以是气体燃料和液体燃料。辐射段上部侧墙向内倾斜,以加强传热效果。并联的多根小直径管由大压降的猪尾管均衡每根管中物料量。高温裂解气采用二级急冷技术回收高温热量。此裂解炉为管式裂解炉中裂解温度最高(石脑油原料中深度裂解的裂解温度约900℃),停留时间最短(约0.065s),烯烃收率最高(高出常规裂解炉约10%~20%),操作周期最短(约7~20天)的裂解炉。反应管材质为Incloy 800,新一代的反应管采用强化传热的内螺旋管结构(以前为圆管),操作周期有所延长。适用于乙烷至减压柴油各种裂解原料。
